Trapped in a mansion filled with vampires and their human cattle, an amnesia-ridden detective must figure out how he got there, how to get out – and who to trust.

Hi Lempicka - I agree.

I think with "amnesia-ridden" it's suggested he'll need to figure how he got there - so perhaps not necessarily for the logline.

Trapped in a mansion filled with vampires and their human cattle, an amnesia-ridden detective must figure out how to get out ? and who to trust.

I'll work on this.

I like the set-up, but I wondered what part the detective's amnesia plays in this? Also, if he's trapped in a mansion filled with vampires, surely his most pressing need is to escape (not figure out how he got there).
